I have a project that requires an 8051 variant that can do the following: 1. Low operating current (around 4mA would be nice) 2. Timer resolution of 1 microsecond Any recommendations would be gratefully received.
Power consumption: If you can use the sleep mode most of the time, virtually any '51 will do. I have heard that TI has some very low power uCs I do not know if they are '51s. Timer resolution is a function of the clock and the higher the clock, the finer the resolution. The best resolution I know of is ib the PCA of the Philips P89c51Rx2 and P89C5166x chips which can have a resolution of clock/2. Erik
